videotext: ioctls changed to use _IO macros

From: [email protected] (Michael Geng)

This patch switches the videotext drivers over to use the _IO macros for ioctls. video_usercopy() works correctly then. The drivers will also map the old to the new ioctl numbers to make sure old apps don't break.

The patch also updates Documentation/ioctl.h to reflect that change. and deletes a unused struct in include/linux/videotext.h.
